<P>PROBLEM TO BE SOLVED: To provide a method of making an LCD module securely operate with a clock signal and image data output from a DSP. <P>SOLUTION: An LCD control system includes the LCD module, the DSP which generates the clock signal and the image data to be output to the LCD module, and a clock frequency division circuit which converts the clock signal to a clock signal of lower frequency. The DSP generates an output image data having pixels increased in a horizontal direction so that when the clock signal to be output does not meet conditions under which the LCD module operates, the image data is expanded in lateral width at a magnification ratio, matching a multiple of the clock signal, to the frequency of the clock with which the LCD module operates, and the clock frequency division circuit converts the clock signal so as to meet conditions under which the LCD module operates, and outputs the converted clock signal and the output image data to the LCD module. <P>COPYRIGHT: (C)2012,JPO&INPIT |
